Then the rarrier of a pneuuiatir tube Weten] is in motion, the rover is at. the rear end of the earrier` and the rontents presa4 against the Cover, due to the momentum. and when the Carrier negotiates` a eurve, it Sloway down but instantly speeds up again on learning;r a straight Seetion ot' the tubes. This variation in Speed causes the eoutents of the. carrier to bump or jolt against the eover and with ordinary earriers will not infrequently result in the rover being fon-ed open, which is objeetionable for obvious rea Sons.

With the present deviee. the aeridental opening of the earrier duringr transit is inipoible., although the Cover ran be readily latehed and unlatehed, and the device is extremely Simple and inexjnnsive in eoustruetion, as well an being ronipart and thorw oughly eliieient.
